APPARATUS FOR FEEDING FLOUR TO B'OLTlNG-REELS.

SPECIFICATION forming part 'of Letters Patent No. 287,097, dated October 23, 1883, Application filed July 13, 1883. N o model.)

To aZZ whom it may-concern:

Be it known that I, ELGIN L. CoNKLIN, a citizen of the United States, and a resident of Corning, in the county of Steuben and State of New York, have'invented certain new and useful Improvements in Apparatus for Feeding Flour to Bolting-Reels; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective View of aboltingreel, with parts of the outer casing broken away to show my improved apparatus for feeding flour or other materials into bolting-reels in operative position. Fig. 2 is a perspective view of my improvement detached from the reel. Fig. 3 is a longitudinal vertical sectional view taken on line at a, Fig. 2. Fig. 4 is a perspective detail view of the feeding-screw, and Fig. 5 is a detail view of the lower part of the bracket.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to apparatus for feeding flour or other material into centrifugal or other bolting-reels; and it consists in the improved construction and combination of parts of an apparatus adapted to feed flour into a centrifugal or other bolting-reel in a continuous and even spray, as will be hereinafter more fully described and claimed.

In the accompanying two sheets of drawings, A represents the frame of a centrifugal bolting reel to which my improvement is adapted to be attached. B indicates the cylindricalbolting-reel, one end only of which is shown in the drawings; 0, a wire trough over the head-of the reel, in which conveyerbrushes 0 revolve, the said trough being provided at one end with a drop-valve, 0, through which is passed any hard substance which will not admit of being brushed through the wire trough; and D, a lower trough, having a revolving right-and-left spiral, D, adapted to feed the grain toward the center of the trough. The above-mentioned parts form no portion I of my present invention.

E represents a bracket, which is pivoted adjustably to about the center of a cross-beam, A, forming part of the frame A, by means of a screw-bolt passing through its lower extremity, and a thumb-screw or screw-bolt, F, working in a transverse slot or enlarged hole,

F, in the lower part of the bracket. The ends of the arms E of the bracket E are constructed to form journal-boxes, F, in which a shaft, G, is supported. Upon the top of the journal-boxes are oil-cups H, through which the axle G and its bearings may be lubricated. Upon the outer end of the shaft G is secured a friction-pulley, I, consisting of a disk, I, secured upon the shaft by means of a screw, A, passing through a collar upon the outer face of said disk; adisk, 1, corresponding in size to the disk I, and a disk, J, of leather or other suitable material, and of greater diam- 7o eter than the disks 1 and I, and secured between the disks I and I by screw-bolts J passing through the three disks.

K represents a metal trough or casing, which is secured to the bottom of the lower trough, I), previously referred to, at or near its center, the inner open end of the casing K being opposite the-central opening of the revolving reel B. i The inner end of the shaft G passes through an opening in the outer head of the casing K, and extends within the said casing for itsentire length. Upon that end of the shaft which is within the casing K is secured a feeding-screw, L, consisting of a cone-shaped core, L, secured upon the shaft with it largest end toward the inner open end of the casing K, the core being preferably made of wood, and covered with tin or other suitable material, which is secured to the wooden core by small screws, and two spiral flanges, L, ex- 0 tending from end to end of the cone-shaped central piece, L.

M indicates a slide in the outer closed end of the casing K, through which air may be admitted into the said casing to facilitate the 5 cooling and feeding of the flour or other ma terial, as will be hereinafter described.

My improved apparatus is secured in operative position by fastening the lower end of the bracket at or near the middleof thecross- 10o beam A of the frame A by means of a screwbolt passing through its lower extremity, and

a thumb-screw or screw-bolt, F, working in a transverse slot or enlarged hole, F, in the against the rim of the flange-pulley N. The

casing K is secured to the lower trough, D, at or near its center, so as to receive the flour or other material which is fed to the center of the said trough, the inner open end of the casing K being opposite the central opening of the revolving reel B.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of my improved apparatus for feeding flour into bolting-reels will readily be understood without requiring further explanation.

It will be seen that by constructing my improved apparatus in the manner described the feed-screw L will feed the flour or other material evenly and steadily into the boltingreel, and by placing the largest end of the cone-shaped feeder L toward the inner end of the casing K it will act as a suction-fan, and thereby facilitate the feeding of the flour or other material into the bolting-reel. By constructing a slide, M, in the outer closed end of the casing K, the air is admitted into the bolting-reel directly through the feeding-chamber K, and the air thus admitted, under the influence of the cone-shaped feeder L, which acts as a suction-fan, will form a circle or become rarefied, so as to cool and feed the flour or other material in a spray as it enters the reel, so that it feeds close up to the reel-head, and I am thereby enabled to utilize the entire inner surface of the cloth which covers the bolting-reel, thereby largely increasing its capacity, while, when the flour is fed into the bolting-reel through a spout of ordinary construction, it travels from eight to twelve inches in the reel before it falls upon the cloth, so that a loss of from one-twelfth to one-eighth of the wearing-surface of the cloth is sustained. By constructing the bracket E with the transverse slot or enlarged hole F near its lower end, through which a thumbscrew or screwbolt, F, is inserted, the spiral spring 0, previously referred to, is enabled to draw the friction-wheel I firmly against the inside of the rim of the flange-wheel N when the periphery of the friction-wheel has become worn by continued friction. It is obvious that shaft G may be driven by any other suitable means.

Having thus described my invention, Iclaim and desire to secure by Letters Patent of the United States i 1. The combination of abolting-reel, a wire trough provided with revolving spiral brushes and having at one end a drop-valve, a lower mitair to the reel through the feeding-chamber K, at or near its center, in direct contact with the material, the said feeding-screw L revolving in the casing K, and consisting of a coneshaped central piece having its largest end toward the inner open end of the feeding-chute K, and provided with spiral flanges extending from end to end, and adapted to feed the flour or other materialinto the bolting-reel in an even spray, and flange-pulley N, secured upon the outer end of the main drive-shaft of the bolting-reel, andadapted to transmit mo tion to the friction-pulley I, all constructed and arranged as and for the purpose shown and set forth.
